Reaction Steps

When the product of Step D was substituted for N-(6,6-dimethylbicyclo[3.1.1]heptan-2-yl)-4-(4-hydroxybut-1-ynyl)benzene sulphonamide in Example 18, Step C, the identical process afforded the title compound in 92% yield, as pale paste. 1H-NMR (CDCl3) 8.40 (broad s, 1H); 7.86 (s, 1H); 7.37-7.32 (m, 3H); 7.11 (d, 2H, J=8.07 Hz); 7.05 (d, 2H, J=8.07 Hz); 4.19 (t, 2H, J=7.17 Hz); 3.72-3.63 (m, 4H); 2.66-2.59 (m, 4H); 1.68-1.60 (m, 4H).
